Preliminary Operating Considerations
This chapter explains how the RTD module and the SLC processor
communicate through the module’s input and output image. It lists the
preliminary setup and operation required before the RTD module can
function in a 1746 I/O system. Topics discussed include how to:
•
enter the module ID code
•
address your RTD module
•
select the proper input filter for each channel
•
calculate the RTD module update time
•
interpret the RTD module response to slot disabling
The module identification code is a unique number encoded for each 1746
I/O module. The code defines for the processor the type of I/O or specialty
module residing in a specific slot in the 1746 chassis. With APS version 5.0
or later, select the 1746–NR4 RTD module from the list of modules on the
system I/O configuration display to automatically enter the ID code. With
earlier versions of APS (version 1.04 through 4.02.01), you must manually
enter the module identification code when configuring the slot.
To manually enter the module ID code, select
(other)
from the list of
modules on the system I/O configuration display. The module ID code for
the RTD module is shown below:

information is required. The
module ID code automatically assigns the correct number of input and output
words.
